Filter

The Filter object lets you create a textual filter of the type used by the Find tool and commands such as Copy to control recursive operations.

Use the dopusfactory.Filter method to create a new filter object. Once you have a Filter object you can:

• Use the item.MatchFilter method to see if a file or folder matches the filter.

• Apply the filter to a command with the command.SetFilter method.

Property Name	Return Type	Description
lasterror	object:filterparseerror	If valid returns False you can use this property to discover information about the error.
valid	bool	Returns True if the filter was created successfully (i.e. no errors were encountered in parsing the filter text).

Method Name	Arguments	Return Type	Description
Add	<string:clause> or <object:Filter> [<string:conjunction>]	bool	Adds a clause to the filter. If provided as a string, the clause will be parsed and the method returns True if parsing was successful. If parsing fails, use the lasterror property to find out why. Alternatively, you can add another Filter object. The clause string must be a fully formed textual filter clause. For example, size match > 2 mb The optional conjunction string lets you choose whether the clause is joined via and or or. If not specified, the default is and.
Clear	none	none	Clears the contents of the filter.
Set	<string:clause> or <object:Filter>	bool	Initialises the filter with either a string or the contents of an existing Filter object. If provided as a string, the clause will be parsed and the method returns True if parsing was successful. If parsing fails, use the lasterror property to find out why.
